A nurse is preparing to administer exenatide 10 mcg subcutaneous every 12 hr. Available is exenatide 250 mcg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.04"]
Determine the total dosage:
The client is prescribed 10 mcg of exenatide.
Calculate the volume per dose:
The exenatide solution contains 250 mcg per mL.
The nurse needs to administer 10 mcg per dose.
To find the volume per dose:
250 mcg / 1 mL = 10 mcg / x mL
250x = 10
Dividing both sides by 250, we get:
x = 0.04 mL

Correct Answer is ["1.5"]
Explanation
Determine the total dosage:
The client is prescribed 500 mg of cefazolin.
Calculate the volume per dose:
The cefazolin solution contains 330 mg per mL.
The nurse needs to administer 500 mg per dose.
To find the volume per dose:
330 mg / 1 mL = 500 mg / x mL
330x = 500
Dividing both sides by 330, we get:
x = 1.515 mL
Round the answer to the nearest tenth:
Rounding 1.515 to the nearest tenth gives us 1.5 mL.
Correct Answer is ["0.7"]
Explanation
Convert the child's weight from pounds to kilograms:
There are 2.205 pounds in 1 kilogram.
Divide: 66 lb / 2.205 lb/kg = 30 kg.
Determine the total dosage:
The child is prescribed 0.55 mg/kg of chlorpromazine.
The child weighs 30 kg.
Total dosage is 0.55 mg/kg x 30 kg = 16.5 mg.
Determine the volume per dose:
The chlorpromazine injection contains 25 mg per mL.
The nurse needs to administer 16.5 mg per dose.
Divide 16.5 mg / 25 mg per mL = 0.66 mL per dose.
=0.7mL per dose.
